for file in sourcepath:

 

    if m.endswith('.sql'):

                no_of_red=line.count('red')

                sys.stdout.write(line.replace('red','RED'))

                count += no_of_red

        filedata=inputfile.read()

        freq=0

Answer 1

if(member(message.author)) {
     console.log(message);  //Первый вызов
     request.post({url:'http://url.ru/', form: {new:'1', id:id, link:link}}, (err,httpResponse,body) => { 
    console.log(message);  //Второй вызов
    })
}

Answer 2

Yes, you can do it with python from the command line:

py -x "x.replace('WHAT', 'TOWHAT')" < inputfile.txt > outputfile.txt

This is if the file is text. If binary, then a little differently, but in binary you need to carefully change this, the format may float.
If you need to exclude the replacement of the same characters as part of other words, then like this:

py -x "re.sub('(\W)What(\W)', '\\\1ToWhat\\\2', x)"" < inputfile.txt > outputfile.txt

Or you can not invent bicycles, but do it via sed from the command line
